I installed Gentoo on my Laptop last week without any problems.
Since Monday I try to install it on my main machine. The
installation failed the 7th time now with the same error, so I am
quite sure it is a bug.
I use Gentoo 1.2 stage 1 CD.

I follow the build docs exactly, and everything works fine until the
first "emerge system"... the error always happens while installing the
Perl package:

No one experienced the same Problem?
What could be the reason, that this happens?
I'll try Gentoo 1.3b today.... hopefully this brings
some difference =/_________________Gentoo Linux/Sparc Developer

I don't know if you fixed your problem yet or not, but I was having the EXACT same problem with perl-5.6.1-r5 with gcc-3.1.1-r1... I was using "-march=athlon-tbird -O3 -fomit-frame-pointer -funroll-loops -malign-double -maccumulate-outgoing-args". Python was also breaking in strange ways (though I wouldn't find out until after Perl got the sandbox error), which led me to a lot of "starting over." I played around with the optimizations (I wanted to figure out exactly which one was causing it, so that I could at least use some of them). Turns out it was the one I least suspected (and tried removing last of course), lil' ol' -malign-double. If that was one when I was bootstrapping AND/OR during emerge system, it would produce the sandbox error and break python.
